A protective cover for electronic equipment automatically expanding by the spring action of a pair of telescoping arms (24) having a cover (48) of resilient material attached between. The arms (24) are positioned contiguous with a pair of bases (20) that are located parallel with each other on the floor on either side of the electronic equipment with a hinged cover enclosure (50) between the ends forming a "U" shape. The arms (24) are connected on the ends by a strut (26) holding the cover (48). Solenoids (58) retain the arms in a tensioned position and when electrically actuated release them. The spring action pivots the arms with its accompanying cover completely enveloping the equipment. A lever (64) arrangement overrides the solenoid action manually releasing the arms. The device is reset by manually rotating and compressing the arms while folding the cover (48) into the enclosure (50). The object is to protect expensive equipment from fire, smoke and water damage if a fire is in the vicinity.
